The ASTM A320 specification, originally approved in 1948, covers alloy steel and stainless steel bolting materials for low temperature service.

ASTM A182 Gr F1 Blind Flange is a solid disc used to block a pipe or create a stop. It is similar to an ordinary flange, with mounting holes around it, and the sealing ring is machined into a mating surface.

The high lead content in STM A320 grade L7M AS bolts results in relatively low ductility and plasticity.

ASTM A193 Grade B7 is a standard material specification for chromium-molybdenum alloy steel fasteners for use in high tensile, high temperature and special purpose applications.

These are flanges with creep strength and high resistance; therefore, steel threaded flanges help them work in the petrochemical industry.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

Alloy seamless steel pipes are mainly used for high pressure and high temperature pipes and equipment such as power plants, nuclear power plants, high pressure boilers, high temperature superheaters and reheaters. It is made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel, processed by hot rolling (extrusion, expansion) or cold rolling (drawing).

The heat treatment could be heat treated according to any of the WPHY 52 specification by either tempering, normalizing, quenching or stress relieving.A860 refers to the high quality of the fittings.

ASTM A182 Grade F5 Flanges are suitable for connecting pipes of small bore size and without the requirement of welding. ASTM A182 GR F5 Flange belongs to the ASTM A182 specification. The dimensions of the flanges vary according to the ANSI, ASME and DIN standards. The flange sizes range from ? inches to 36 inches in nominal bore sizes. Navstar Steel is a leading supplier and manufacturer of these flanges in various sizes and types.

The alloy must be cooled for heat treatment prior to AISI AS F11 Hex Bar. All parameters of the heat treatment procedure are set by the specification, including the type of heat treatment, austenitization/solution temperature, and alloy steel F11 A182 bars.

The alloy has great mechanical properties at subzero temperatures.For catering to the needs of our customers better, it is essential that we manufacture Monel Pipe Fittings in different types, with each one serving some specific purpose.

There are other different types of ASME SA 182 AS Pipe Flanges such as the weld neck flanges and socket weld flanges each specified for a particular role.

A335 P9 steel pipe material also contains manganese, silicon, carbon and phosphorus in its composition. The addition of these materials makes the material stronger with higher yield and tensile strengths. Due to the high chromium content, the redox effect is high.

A335 P22 is a seamless tube made of ferritic alloy stainless steel. Chemically, the alloy of SA335 P22 material contains trace amounts of carbon, manganese, sulfur, silicon and phosphorus. The main additives in the alloy are molybdenum and chromium, which give stainless steel excellent mechanical properties. Tensile strength, corrosion resistance, hardness and other properties are enhanced and improved. Molybdenum reduces the brittleness caused by the addition of chromium.

The carbon content in the Sa182 F9 flange is lower, so the weldability of this alloy is much better. Generally, higher carbon content in alloys promotes intergranular corrosion, especially during high heat treatments such as welding.

SA182 plate flanges can be used in environments where mildly aggressive compounds are present. It can also be used in non-corrosive applications as well as aggressive applications at temperatures between -30?C to +650?C.

Several ANSI/ ASME standards use materials that are forged or cast to produce Cast AS Blind Flanges.

Stainless steel is a versatile alloy is considered to be amongst the most widely used metals across the world.Stainless Steel A403 WP304 contains higher chromium and low carbon content.

Weld Neck Flange is flanges that designed to be joined to a piping system by butt welding. This kind of flange include lots of specification.

SA182 F5 Plate Flange can be used in those environments where there is a presence of mild corrosive compounds. It can also be used in non-corrosive applications as well as in erosive applications at the temperature between ranging between -30oC up to +650oC. ASTM A182 Grade F5 Flanges in conditions characterized by increased levels of carbon dioxide (CO2), hydrogen sulphide (H2S), and as well chlorides (Cl). The highlight of A182 F5 Steel Slip On Flanges are Precise plan, Accurate measurements, Resistant to corrosion, Less costs, pitting and crevice resistance.

Production of low alloy steel materials of different specifications. A335 is a specification for seamless ferritic alloy steel pipes. These alloy steel seamless pipes are used for high temperature service. There are also high alloy steel materials. There are different grades in this material specification. There are grades P1, P2 to P91 and P92. The most commonly used grades are p5, p9, p11, p22, p91 and p91.

Custom pipe flanges can be manufactured from a variety of materials and material grades. Carbon steel is a popular solution, as are stainless steels and specialty alloys, depending on the industry. Sheet and forging are also common, and titanium and aluminum are also suitable for lightweight jobs.

HastelloyC-276 (Hastelloy) is a tungsten-nickel-chromium-molybdenum alloy with extremely low silicon-carbon content and is considered to be an all-around corrosion-resistant aluminum alloy. The key moisture-resistant chlorine, various air-oxidizing fluorides, isopropyl titanate solutions, hydrochloric acid and air-oxidizing salts, have good corrosion resistance in ultra-low temperature and standing temperature sulfuric acid. Therefore, in the past 30 years, it has been widely used in extremely corrosive natural environments such as chemical plants, petrochemicals, flue gas desulfurization, pulp and paper industry, and environmental protection.

Corrosion resistance

The aluminum alloy has the following characteristics: 1. It has good corrosion resistance to most corrosive substances under the two conditions of air oxidation and repair. ¢ÚIt has good resistance to pitting corrosion, void corrosion and intergranular corrosion. The higher content of Mo and Cr makes the aluminum alloy resistant to corrosion by chloride ion content, and the W element further improves the corrosion resistance. At the same time, Hastelloy C-276 aluminum alloy is one of the only types of raw materials that are resistant to wet chlorine, hypochlorite and chlorine dioxide saturated solutions. Ester solution has obvious corrosion resistance. It is one of the very few raw materials that can be used as a hot sulfuric acid saturated solution.

Carbide solution treatment, also known as solution annealing, is a process in which fasteners or stainless steel rods are heated and then water quenched to ensure maximum corrosion resistance. A193 Grade B8 Grade 2 bolts are strain hardened after carbide solution treatment to improve strength properties and reduce the potential for wear.

High alloyed types of steel are favored in the plumbing industry for use in extreme conditions, be it hot or cold, or subjected to rough service. This is because a combination of chemistry and proper heat treatment can result in a strong and flexible pipe that can withstand blows. Alloy pipes are often favored by the oil and gas and power generation industries due to their toughness.
